I belong to NAR because of the support agents and buyers/sellers receive. But, come on, there are PLENTY of unethical Realtors. Being a Realtor does not guarantee an agent will have ethics. Dual agency plays a huge roll in this in California, and CAR does nothing about it, so the problem goes on and many brokers even make it financially beneficial for agents to keep both sides of a sale in house. There's no way that helps a seller. So, there are many agents, whose basic responsibility should be to their seller's financial interests, completely and knowingly mislead them for their own financial benefit. Because of this, some states have made dual agency illegal.
People who need a lobby to force them to be ethical human beings, aren't all of a sudden going to become ethical people, as is very evident these days. Other than that, I fully support NAR.
